Problem conclusion

• The internal threshold for the CPU usage of the subtask
  preparing the performance data for the PE Workstation Client is
  increased to allow higher CPU consumption for the maximum
  supported autorefresh rate, which is once per second.
  When CPU usage for a subtask of DB2 PE exceeds the internal
  limit all internal traces are started to capture a possible loop
  condition. When the CPU usage thereafter gets back to normal
  usage conditions the traces are automatically switched off.
  When the high CPU usage condition persists a dump is taken in
  addition to the traces to preserve data for analysis. After
  about 10 minutes of consecutive detection of high CPU conditions
  the causing subtask will be terminated and restarted.
